    Statement introduced in Junos OS Release 11.3 for the QFX Series.

    Description

    Configure the maximum number of link-state advertisements (LSAs) that are not generated by the router or switch in a given OSPF instance.

    Default

    By default, OSPF database protection is not enabled.

    Options

    ignore-count number—Configure the number of times the database can enter the ignore state. When the ignore count is exceeded, the database enters the isolate state.

    Range: 1 through 32

    Default: 5

    ignore-time seconds—Configure the time the database must remain in the ignore state before it resumes regular operations (enters retry state).

    Range: 30 through 3,600 seconds

    Default: 300 seconds

    maximum-lsa number—Configure the maximum number of LSAs whose advertising router ID is different from the local router ID in a given OSPF instance. This includes external LSAs as well as LSAs with any scope, such as the link, area, and autonomous system (AS). This value is mandatory.

    Range: 1 through 1,000,000

    Default: None

    reset-time seconds—Configure the time period during which the database must operate without being in the ignore or isolate state before it is reset to a normal operating state.

    Range: 60 through 86,400 seconds

    Default: 600 seconds

    warning-only—Specify that only a warning should be issued when the maximum LSA number is exceeded. If configured, no other action is taken against the database.

    warning-threshold percent—Configure the percentage of the maximum number of LSAs to be exceeded before a warning message is logged.

    Range: 30 through 100 percent

    Default: 75 percent
